A couple of questions: - Does it matter which 'PHLASH16.EXE' I use? I'm tempted to try v.1.7(or v.1.9) from the Acer web site since v.1.4 was the original which I wanted to upgrade anyway and v.1.20 was what caused the current BIOS/bad flash issue.
- Also, if the process fails, presumably retying again will cause no further issues? ie: I don't suppose it can get any worse than a bad BIOS flash (lol).
Thanks
in theory it would not matter which version. but it would be best to use the one from the acer web site if they provide one.

Overall steps:
o. use phoenix crisis recovery tool to create a boot disk
o. replace the bios.wph with the oldest bios version (mam110.wph)
. This floppy now have mini dos, phlash16.exe, and bios.wph
o. fn+esc to load the bios file, you will hear the floppy reading the file (~ 2 mins) a silence period (~3 min).
o. if successfully, the laptop reboot, you will see the bios screen.
At this point, you would want to upgrade the laptop to appropriate bios version
o. create a bootable CD ROM that would boot into the appropriate OS, load cd rom driver, and assign appropriate drive. This is important for the next step.
o. create a cd rom that contains all bios version into folder. For example, i have v114, v117, v119. The reason is that i suspect each version use the appropriate phlash16.exe base on the time the bios is created.
Note: if you can setup the bootable CD that would also contains the above folders, that would be better, as you don't have to reject the bootable cd and insert the bios cd.
o. after you have the above create, you should know what need to be done from this point on. Basically the steps involve around boot up, navigate/select the appropriate bios, run the appropriate phlash16.exe (I manually run one of the below, one at a time.)
phlash16 /x /mode=3 /BBL mam114.wph
phlash16 /x /mode=3 /BBL mam117.wph
phlash16 /x /mode=3 /BBL mam119.wph
1. have the phoenix crisis recovery tool.
2. have the bootable cdrom with all the bios version in appropriate folder
3. know that the fn + esc would force the machine to read/load
bios in special recovery mode. Note, this is also a blind mode as you can not see anything
4. remove the HD so it's not part in the boot order
5. I don't have autoexec.bat for the intitial recovery with the fn + esc and the bios load just fine. I believe the process look for phlash16.exe and the file bios.wph
Tools used
o. usb floppy drive
o.
